The only one I really don't like is Rotom. I mean it's just so stupid. A fridge...? I mean... seriously wtf were they thinking? Basing a pokemon on a bunch of appliances? Ergh. It made me really really scared for pokemons fate when I discovered Rotom.
Read this before contributing stuff that is pointless.
Rotom's forms are not 'based on appliances'. They actually are those items, just possessed by Rotom itself. Hence the reason each item isn't a seperate Pokémon in the Pokédex.
